Long cycling droaning sound. Louder at night. Louder and more constant since new Apple UFO campus opened. Originally started one night, then got weaker. Few weeks later steered to grow more constant and louder. Coming more from the ground. Sounds more mechanical than natural. Just that I started to notice the sound as the new Apple campus was in its final stages of completion. Since they have begun moving people in Jan 2, 2018, the sound has been more regular, louder, deeper, more intense and constant day and night.
